THE launch of quantum computer Qianshi is a milestone in the development of quantum technology. For the first time, a quantum computer is accessible in the public ICT network, and people are able to connect to it using their personal devices. It has only 10 quantum bits (qubits), with capabilities of a traditional computer (Baidu launches quantum computer in China and gives people access via PC, smartphone or the cloud, The Star, Aug 26, 2022).
Quantum computers can be far more powerful than any supercomputer, capable of breaking any conventional encryptions within a short period. In the lab, quantum computers with performance matching the supercomputers on specific problems have been realised.
